DEVICE FORSE IN DUMPING WHEELBARROWS Application led December 8, 1924.r Serial N'o. 754,551.

To all whom t may concern:

Be it known that I, SEVERIN KLEVEN, a citizenv of the United States, residing at Sisseton, in the c ounty of Roberts and State of South Dakota, have invented certain new and useful Improvements in Devices for Use in Dumping Vheelbarrows, of which the following is a specification.

My invention relates to devices for use in dumping wheelbarrows. An object is to provide a device which is'so constructed that it may be hung from the top of the concrete forms and which will support a plank inV inclined position to constitute a runway for the wheelbarrow when loaded with concrete. Another obj ect is to provide a device of this character having means for preventing the wheel of the wheelbarrow from slipping backward while the dumping operation is performed. Another object is to provide aY device which is adjustable in'order to change the height at which the inner end ofv the Another object is to plank is supported. provide a device which is adjustable in order to change the distance of the wheel of the wheelbarrow from the concrete form when the barrow is in dumping position.

The full objects and advantages of my invention will appear in connection with the detailed description thereof, and the novel features of my inventive idea will be particularly pointed out in the claims.

In the accompanying drawings,-

Fig. 1 is a sectional view illustrating my device in use with the wheelbarrow shown in dotted outline. Fig. 2 is a side eleva tional view. Fig. 3 is a front elevationalV view. Fig. 4 is a view in horizontal section on the line 4 4 of Fig. 2.

.As will be understood from the drawings, the device consists of two yoke members, the

arms of one member being pivotally attachedk at their vends to intermediate portions of the Y arms of the other member, and the arms of made in two parts adjustably held tog-ether by bolts 26 each ladapted topass through and` 24 near theirrear portions are curved Vvupwardly andvconnected by the .crossbar 28 which inclines downwardly when the device is set up for use asshown in Fig. 1. j

The operation and advantages of-my invention will be obvious in connectionwith the foregoing description. The hooks 18 and 20 are engaged over lonev of the walls W of concreteforms in the manner shown in Fig. 1 and the forward end of a plank 'P is pushed underneath the crossbar'28 andover the crossbar .10 so that the plank is brought close tov but not in engagement with the yany one of a series ofholes. The arms 22 form The crossbar 10 has upwardlyj extending studs 80 which are beveled on the.

forward side to prevent the plank slipping ahead. Crossbar 28 has downwardly-extending studs 82 which are' beveled on the i rear side in order to prevent the plank slipping rearwardly. When the plank issupportedin this position it serves as a runway for a wheelbarrow Vloaded lwith vconcrete which is, to be deposited in the forms. The

wheel of the wheelbarrow drops down inthe front of the crossbar 28 and prevents backing up of the wheelbarrow when it is tipped to unload the concrete. The length of the arms 22 and 24 may be adjusted by means 1 v of the Vbolts 26-so that the crossbar 32y will be properly positioned for different makes of wheelbarrows. The length of the arms 12 and 14 may be adjusted so as to maintain the forward end ofthe plank at the right` height by means ofthe bolts 16. On ac# count of the pivotal attachment of the two yoke members to each other the device ac-f commodates itself to different lengths of planks and when not in use it can be folded so as to occupy a much smaller space. In

order that the wheel of the barrow may pass smoothly over the crossbar 32 the rear maricc gin of the latter is preferably thinned down into wedge shape and for this purpose the middle portion of the crossbar may be extended rearwardly as shown.
